4) Improvement of dust sending function and improvement of handling workability
It is configured so that

A processing cylinder (7) provided in the threshing unit (4)
The processing exhaust port (37) at the rear is viewed from the
5) Open between the third opening (44) and the suction and exhaust fan.
(Using the exhaust-side dust-feeding power of 35, the processing cylinder (7)
Efficiently sent to the third exit (44) and from the processing cylinder (7)
Dust is stagnant on the rear upper surface of the swing sorter (26).
It is configured to eliminate the throat.

Further, the suction and exhaust fan (35) has a conical wind direction portion (3) diverging rearward at the rear end of the shaft boss (35a).
5b) is integrally formed, and when the suction air from the upstream of the fan (35) flows to the downstream side, the wind direction portion (35b) allows the air to flow over a wide area to the outside of the outer diameter portion, so that the outer diameter is reduced. It is configured to enable suction of forward wind without wind back on the outside.

This embodiment is constructed as described above, and during the rocking and sorting operation of the threshing grain by the rocking and sorting machine (26), the sorting wind from Karino (32) is fed by the first conveyor ( 33) After passing through the upper chaff sheave (29), along the upper surface of the fourth gutter (38), the fourth opening (4)
3) Without blowing up in the direction, the suction and exhaust fan (3
With the suction force of 5), the air is sucked in along the inside of the fourth gutter (38), and the air is exhausted out of the machine from the third opening (44). As a result, the blowing of wind from the fourth port (43) to the cutting cutter (36) side as in the prior art is also prevented, the accumulation of dust and the like on the fourth gutter (38) is eliminated, and the fourth port ( 43) It is possible to greatly reduce the outflow of grains by the wind from the wind and the collection hindrance of stabs due to the accumulation of dust. Is facilitated by the effective suction wind, and a highly accurate and efficient sorting operation without grain loss can be performed.

The driving source of the suction and exhaust fan (35) may be a feed cylinder (6), a processing cylinder (7), or the like, in addition to the feed chain (5).

In addition, by using an independent motor, the number of rotations is controlled to an optimum value according to the working conditions such as wet material, recirculation, overdrying, mowing start, mowing end, so that the scattering loss of kernels can be minimized. It is also possible to maximize the sorting ability.

Further, since the air suction / discharge fan (35) is provided with a wind direction portion (35b), it can be located in a position deviated from the outer diameter portion of the conventional blade so that the wind does not blow and the wind becomes a blind spot. In this way, the wind can be circulated over a wide area, eliminating dust buildup and clogging due to the blowback of wind in the blind spot, and making the flow of the sorting wind a normal wind to further improve the sorting performance. is there.
